REGENERATIVE coKE OVEN.

EVENCE COPPE,4 OF BRUSSELS, BELGIUM.

REGENERATIVE conn-ovina.

To Aall Lb/Lam t may concern:

Be it known that I, EvENon Corrnn, subject of the King of the Belgians,residing at 103 Boulevard d'eVVaterloo, Brussels, Belgium, have inventeda new and useful Improvement in Regenerative' Coke-Ovens and I do herebvdeclare the following to` be a full,

clear, and exact description ofthe same.

The different systems of regenerative cokel Ovens may be divided .intotwo classes, ac-v cording to which they comprise either a. separateregenerator for each oven, or a common regenerator for the entirebattery.

Both herent advantages and drawbacks. lf on the one hand the arrangementof a single regenerator under all ovensr of one and the saine batteryresults in obtaining an automatic regulation ofthe working of the oven,throughI the uniform temperature of the hot air distributed into thedifferent side walls, on the other. hand said arrangement suppressestheindependence which tween the' regenerators in the systems withA aseparatezregenerator for each oven. y n

Said independence while advantageous in several respects gives rise toall the drawbacks inherent to said system, 'z'. e. the'mutua'ldependence of the ovens and' of their respective regenerators, and thesuppression of the automatic regulation of the working of the oven,which cannot Vbe produced by' separate regenerators, distributing the'hot air at a density and a temperature that are obviously variable fromone regenerator to the other. 4

The present invention has for its object a system of regenerative cokeoven combining the advantages of both arrangements above described, asit insures the independence of the different regenerators while insuringat the same time the independence between each oven and regenerator,located beneath Such oven, by means of an arrangement insuring uniformtemperature of the hot air, or of the hot gases, or of the gas and airsi multaneously, beforel their distribution in the different side walls.

It consists principally in that the combustion agent, the temperature ofwhich is to be equalized, is collected at its outlet fromtheregenerators, into a mixing collecting Hue Specification of LettersPatent.

common to all regenerators, after which it passes into a distributingflue from which it is distributed to the ovens at a uniform temperature.

Figure l is a schematic view the principle of the invention.v

F 2 is a vertical longitudinal section taken through anyoven, that is, atransverse vertical section through a bench of ovens and regenerators.

Fig. 3 is a horizontal section of the chimney and reversing valve.

Figs. 4, 5, and 6 are sectional views taken on the lines M-,N, O-P, andR-S, re:-r spectively, of F ig. 2.

F ig. 7 is aV schematic view illustrating av form of the invention inthe case of ovens heated by means of blast-furnace gases or the like.

Fig. 8 is a vertical sectional view, showing the general arrangement ofthe several parts of the system illustrated in Fig. 7.

Fig. 9 is a sectional plan view of the chimney and of the reversingdevice.

F i'g. 10 is' a sectional view at right angles to Fig. 8, taken on theline X--Y of Fig. 8.

Referring to the embodiment shown in Figs. l to 6 inclusive:

It will be seen that eaeh'roven O of the bench of ovens is arrangedab'ovetwo regen# erators, with regenerators of the R series below theovens and at one side' of the furnace and the regenerators` of the Rseriesy below the ovens and at the other side of the furnace. Y,

The arrangement is such, asjwill now be described structurally, thateither series of regenerators may have continuously passed therethrough,in parallel, the waste gases from the ovens, thereby to transfer andstore a large amount of heat in the series, while' passing thecombustion agent, as air on its way to the ovens, through the'otherseries previously heated as the first series is now being heated,thereby to preheat the air; the air -being thus preheated also passingin parallel through its series; the arrange' ment being also such thatthe function ofthe two series, or the working of the apparatus, may bereversed at desired intervals.

The regenerators of the R series'wh'en acting as preheaters are adaptedto be served illustrating regenerator R1,

in parallel by a main air channel or conduit A, and the regenerators ofthe R1, when so acting, by a similar channel A.

For the purposes of clarity, the passages T and T joining the conduits Aand A and the regenerators othe R and R series, respectively, areomitted from Fig. 1.

The regenerators of the R series, when so acting as preheaters, areadapted to discharge in parallel into a collecting channel or conduit B,the heated air passing thence through a passage K into a distributingchannel or conduit C, and thence to the dii'- erent sole-flues F.

These sole-i'lucs are not indicated in Fig. 1; nor are there shown inFig. 1, passages H leading from the individual regenerators of the Rseries to the collecting channel B of that series, or the passages Uleading from the distributing channel C to the soleues F.

The generators of the R1, series are ar-k when acting asv ranged so thatthey, too, preheaters, may discharge in parallel; they then being servedby elements A', B C, K and U', similar to the elements of A, B, K, C andU associated with the R regenerators.

It will be seen from a comparison of Figs. 2 and 6 that passages yU openinto soleues F.

It will also that similar valves t and Figs. 2 and 6 71. and L, and

be noted from t,

L and L', for the two series of' regenerators R and R1 are provided;although not shown in Fig. 1.

Upon properly setting these valves and the valve W (Figs. 1 and 3),either of the series of regenerators may have through the combustionagent to be heated, While the other series of regenerators has passedtherethrough the waste products of combustion from the ovens, and ineither case any oven or any regenerator may be cut out from the others.

Selecting, for example, the regenerators of the R series, as thepreheating regenerators, it will be seen from a comparison of Fig. 1with Figs. 2, 4f, and 6, that the heated air leaving the regenerator R2is discharged into a common channel B with the air fromthe and theseairs are mixed. In the same way, the air leaving the regenerator R3 willbe mixed in this common channel with the air coming from R1 and B2; andso on.

Thus, the air reaching the point a in the case of each conduit Ballotted to each group of ovens, say twenty, of the plurality of groupscomprising the apparatus, will be at a temperature which is the averageof that of all theregeneratorsdischarging into that conduit. In thisconnection note that a conduit K is allotted in Fig. 1 to each group oftwenty rcgenerators. This air arriving at the point a, is drawn bysuction into a dispassed there-v tributing channel C, whence the hot airpasses through passages U to the dierent sole-fines F, according to theproportions regulated by valves, L controlling the entrance of the airinto said sole-fines F.

The arrangement described, on account of the mixing of the air comingfrom a Awhole series of regenerators, insures, a uniform temperature forthe hot air. This in turn insures a natural regulation of the working ofthe battery. There is thus precluded any chance of the cooling of anoven. At the same time, any variation in the working of the battery isavoided, in contradistinction to the known systems of ovens withindependent regenerators. Further, a total independence between theovens and their regenerators is also obtained, by reason of which anyoven may be put out of service without causing interruption in theservice of the corresponding regenerators, and any regenerator may beput out of service without necessitating extinction of the ovens above.l l i Referring nouT to Figs. 7 to 10, inclusive,

there ,is shown an arrangement adapted t0k generators (see R1, R2, Fig.10) being for preheating the air combustion agent.

As shown most clearly in Fig. 7 the incoming gases are passed throughthe channel A or A and the channel D or D and thence led throughtheregenerators R or R to enter the collecting channel C or C', the heatedair is led oil from the air regcnerators on l one side or the other ofthe apparatus, by

way of a conduit or channel C or C while the heated gas is led off fromthe gas regenerators on that side of the apparatus by way of a conduitor channel D or D. The channels B and are connected by a passage K andthe channels B and G are connected by a assage K.

As illustrated in Fig. 10, but notJ in Fig. 7 the gas regenerators ofeither series of regenerators on a side of the apparatus are connectedto the channel D or D by means of passages X.

As indicated in Fig. 9, the gas channels D and D are controlled .attheir inlet ends by valves V and V, branch conduits E and E beingprovided as shown in Fig. 9. The valves V and V, together with the valveW, are used for connecting the uptake Y to one side or the other of theapparatus to control the working thereof.

By properly adjusting valves the l' W, V and 131 V the gas regeneratorsas well as the air regenerators on either side of the apparatus, may beadapted for the heating of air. This is desirable when heating is bymeans of a rich gas. In such case the valve V and V are permanentlymaintained open.

Having now described my invention, I declare that what I claim is In asystem of regenerative coke ovens, a series of regenerators, a pluralityof ovens for which said regenerators are provided, a feed channelleading to the regenerators, said regenerators being disposed inparallel therewith, a collecting channel communicating with saidregenerators whereby the discharges therefrom will be successivelybrought together, an uptake, a plurality of sole-flues into one of whichthe heated body is discharged and from the other of which said body isdrawn by suction to communi- 20 EVENCE COPPE.
